FRANCIS D. HAYWARD, OF MALDEN, MASSACHUSETTS.

RUBBER HEEL FOR BOOTS OR SHOES.

' SPECIFICATION forming part of Letters Patent No. 263,781, dated September 5 1882.

Application filed July 5, 1882. (No model.)

To all whom it may concern:

- Be it known that I, FRANCIS D. HAYWARD, 0t Malden, in the county of Middlesex, of the State of Massachusetts, have invented a new and useful Improvement in Vulcanized Rubher Boot or Shoe Heels; and I do hereby declare the same to be described in the followin g specification and represented in the accompanying drawings, of which- Figure 1 is a bottom view, and Fig. 2 a vertical section, of a heel provided with myinvention, thenature of which is defined in the claims hereinafter presented. Fig.3 is a perspective view of the metallic re-ent'orce of the rubber or elastic body of the heel.

In carrying out myinvention I combine with the vulcanized rubber body of the heel a meiallic re'enforce composed of an annulus or ring, or a portion of such,and a series of teeth or studs projecting down from it.

In the drawings,A denotes the rubber body of the heel, while B is the metallic re-enforce, arranged therein in manner as shown,the said re-enl'orce consisting of the U-shaped ring-c and itsseries of teeth or studs 1), extending down from it. This ring I provide with projections 0, extending from it, in order to centralize it in the mold used for molding the heelbody upon it, such projections, when the reenforce is in place in the matrix of the mold,

being in contact, or about so, with the sides thereof. Having placed the re-enforce in they mold, I force into such mold, so as to thoroughly cover the re-enforce, except at the extreme ends of its studs b, the vulcanizable composition or material to constitute the elastic body of the heel, after which I submit the mold to heat sufficient to vulcanize the said material.

The studs, besides giving to the heel the appearance of being nailed, will protect itsbottom from wear, they being held in place by their ring, or the part from which they may project.

A vulcanized rubber heel so re enforced is not only stronger and more durable than it would be without the re-enforce, but is less liable to slip on either dry or wet ice, the spurs, owing to the elasticity of the rubber, operating to prevent such slipping.

The re-enforce may consist of a rubber plate or a ring" or a strip of rubber suitably bent and provided with a series of studs extending from it.

I do not claim a ree'nforce made with a lip to extend down from it and around it to the level with the bottom of the heel.

What I claim as my inventionis as follows,

viz:

1. The metallic re-enforce consisting of the annulus B, having downwardly projecting studs b, and the outwardly-centralizing pro jections c, all substantially as shown and described.

2. A rubber heel provided with the annular re-enforce B,provided with the projections b c, all substantially as shown and described.
